Recently, Kolla project has requirement to modify[1] the python's

ConfigParser.py code[0].

Python is using PSF license[3], which is GPL compatible. But OpenStack

is using Apache License.

Here is the diff view[2].

I want to make sure: is it OK to re-license ConfigParser.py? If not, what

the solution?
